Dominant epistasis ratio with A as epistatic gene 12:3:1 corresponds to ________________

Dominant epistasis ratio with A as epistatic gene 12:3:1 corresponds to ________________ Correct Answer A/- -/- : a/a B/-: a/a b/b

In case of dominant epistasis, if there is atleast one dominant allele here A in the epistatic locus, the gene combination at B locus will not affect the phenotype. So the combination at B can be written as -/-.
